Thanks Rob for your prompt response. 

The inlet velocity for each of the structure was taken to be 0.021m/s.

Below are the mesh for each of the structures.

SMOOTH STRUCTURE

CACTUS SHAPED STRUCTURE

HORN-STRAKED STRUCTURE

HELICAL-STRAKE

Please, if my meshes are wrong, can you help with best way to go about doing a good mesh.

 

Thanks
